MGS3 HD feels REALLY goddamn good to play on PS3, it has full Anti-Aliasing, it's crisp and SO smooth and runs at 60 frames.
Here's the real kicker, text and Menus and even hair are way nicer and clearer than they are in GZ, Ground Zeroes looks great and all, but it looks so jagged and rough that it feels impractical to play in a night time setting sometimes (It's better on the PS4 but it's still a little rough.)
This kind of goes into my whole idea I've had for awhile now that games should be made to run efficiently before they're made to look pretty, because older games look pretty damn nice when you run them with extra settings that smooth everything out.
In this day and age, especially now on the PS4 and XBONE, there is no excuse for games to not be aiming for a point where they always run in full Anti-Aliasing and even 60 fps, I myself am not prone to dismissing a game based on frame rate, but it is true there's no reason why that shouldn't be the case, always running in 60 would be an argument in favor for consoles as well, since running a game at flat 60 on PC if it's current gen is not necessarily easy for the average PC user.
